I had a good one today, making changes to an existing project I replaced an inner for loop with a do while true and got the error:
I created a new app and copied the whole sub, and all of it's dependencies, there were quite a few. Then started deleting blocks of code. There were about 100 lines of code inside the Do While loop, so didn't notice until I stripped it all down that I had neglected to put an exit in the inner Do while loop
What it boils down to is that I had this:
Which throws the exception above on compilation.
There was no Exit clause which I couldn't see in amongst the rest of the code. Now I know what the problem was the error message sort of makes sense, but I thought it was a bit cryptic at first.
@Erel I will remember this one in future but I don't know if it's possible to catch this situation in the IDE validation, it may be worth it if it is.
